Generalized electromagnetic theorems for non-local plasmonics
Emilie Sakat, Antoine Moreau, Jean-Paul Hugonin
The ultraconfined light of plasmonic modes put their effective wavelength close to the mean free path of electrons inside the metal electron gas. The Drude model, which can not tak…
Reduced lasing thresholds in GeSn microdisk cavities with defect management of the optically active region
Anas Elbaz, Riazul Arefin, Emilie Sakat +20
GeSn alloys are nowadays considered as the most promising materials to build Group IV laser sources on silicon (Si) in a full complementary metal oxide semiconductor-compatible app…
Upper bound for light absorption assisted by a nanoantenna
Emilie Sakat, Léo Wojszvzyk, Jean-Jacques Greffet +2
We study light absorption by a dipolar absorber in a given environment, which can be a nanoantenna or any complex inhomogeneous medium. From first-principle calculations, we derive…
True thermal antenna with hyperbolic metamaterials
Grégory Barbillon, Jean-Paul Hugonin, Svend-Age Biehs +1
A thermal antenna is an electromagnetic source which emits in its surrounding, a spatially coherent field in the infrared frequency range. Usually, its emission pattern changes wit…
Optical Activation of Germanium Plasmonic Antennas in the Mid Infrared
Marco P. Fischer, Christian Schmidt, Emilie Sakat +9
Impulsive interband excitation with femtosecond near-infrared pulses establishes a plasma response in intrinsic germanium structures fabricated on a silicon substrate. This direct…
Tunability and Losses of Mid-infrared Plasmonics in Heavily Doped Germanium Thin Films
Jacopo Frigerio, Andrea Ballabio, Giovanni Isella +16
Heavily-doped semiconductor films are very promising for application in mid-infrared plasmonic devices because the real part of their dielectric function is negative and broadly tu…
